Vitamin D, or the sunshine vitamin, is produced by the skin when it is exposed to sunlight. Many individuals don’t get enough sunlight due to seasonal changes, geography, and lifestyle, and obtaining vitamin D through food alone can be challenging, which can lead to insufficient vitamin D levels. Thorne’s Vitamin D3 Liquid comes from a vegan, sustainable source, and makes supplementation easy with a new and improved bulb dropper to measure precision doses of both 2,000 and 4,000 IUs of vitamin D.
